The input power, w ˙, to a large industrial fan depends on the fan impeller diameter d, fluid viscosity μ, fluid density rho, volumetric flow q, and blade rotational speed ω. what are the appropriate dimensionless parameters?

like poles repel so keep pushing north to north and repels funny to see this

answer: the potential energy decreases from 379 j to 243 j

explanation:

for the law of conservation of energy, the total energy in a system must be conserved. the total energy of the system is given by the sum of kinetic (k) and potential (u) energy:

e = k + u

the total energy is e=675 j, and this does not change.

initially, the kinetic energy is k=296 j, so the potential energy is

at the end, the kinetic energy is k=432 j, so the potential energy is

so, we see that the potential energy has decreased from 379 j to 243 j.
